Child Support in District of Columbia
The District of Columbia calculates child support under an income shares guideline set out in D.C. Code § 16-916.01. The guideline combines both parents' adjusted gross incomes and looks up a basic support obligation on a published schedule. It then divides that amount between the parents based on each one's percentage share of the combined income. DC Superior Court judicial officers apply the guideline in every divorce, custody, or child support case. The Child Support Services Division, part of the DC Office of the Attorney General, is the District's IV-D agency. It helps parents establish, modify, and enforce support obligations.

The income shares guideline
D.C. Code § 16-916.01 requires the court to calculate each parent's adjusted gross income. It uses the parents' combined adjusted gross income to find a basic child support obligation on the Schedule of Basic Child Support Obligations. Then it calculates each parent's percentage share of that combined income. The basic obligation is multiplied by each parent's percentage share to set that parent's portion. The parent who does not have the child living with them primarily is generally the one with the legal duty to pay. The guideline is built around gender-neutral, subsistence-need-based principles written directly into the statute.
Applying through CSSD
The Child Support Services Division, known as CSSD and housed in the DC Office of the Attorney General, is the District's IV-D agency. A parent applies for services through CSSD's enrollment portal or by contacting the division's customer service line. CSSD can help establish paternity, set up a new support order, or collect and enforce an order already in place. The division also offers remote assistance by phone, email, and virtual appointment.
Who hears a DC child support case
DC Superior Court judicial officers decide child support as part of a divorce, custody case, or intrafamily protection proceeding. The court must inquire into a family's child support arrangements even when a party has not specifically requested support. Judicial officers apply the § 16-916.01 guideline to calculate the presumptive amount. CSSD's role is to establish, monitor, and enforce those obligations, rather than to independently set the amount.
Modifying an existing order
Under § 16-916.01, a rebuttable presumption in favor of modification arises in one situation. That is when reapplying the guideline to the parents' current circumstances would change the support amount by 15 percent or more from the existing order. That presumption can be rebutted by proof of special circumstances or substantial reliance on the original order. Separately, a parent can seek modification at any time. This applies when there's a material and substantial change in the child's needs or in the paying parent's ability to pay, even if that change is less than the 15 percent threshold.
Enforcement tools
CSSD monitors and enforces DC child support obligations, which can include income withholding. The division participates in federal IV-D enforcement mechanisms such as tax refund interception for cases that qualify. For incarcerated parents, the statute sets out a specific process for adjusting support once CSSD receives notice and documentation of the incarceration. A parent who does not comply with a Superior Court support order can also be brought before the court and held in contempt.
